[0002] During the weaving process, the warp yarn is subjected to greater tension and friction, and is prone to breakage. In order to reduce warp breakage, improve weaving efficiency and grey cloth quality, the warp yarn needs to be sized before weaving. Sizing can form a layer of size film, making the yarn tight and smooth, thereby improving the yarn's breaking strength and wear resistance. However, the sizing on the grey cloth is not conducive to printing and dyeing, because the presence of sizing will contaminate the dyeing and finishing working liquid, consume dyes and chemicals, and even hinder the contact between dyes and chemicals and fibers, affecting the printing and dyeing quality of the product. Therefore, the fabric must be desized to remove the sizing before dyeing and finishing.
